Configuring ACLs

Overview

An access control list (ACL) is a set of rules for identifying traffic based on criteria such as source IP

address, destination IP address, and por t number. The rules are also called permit or deny

statements.

ACLs are primarily used for packet filtering. "Configuring packet filtering with ACLs" provides an

example. You can use ACLs in QoS, security, routing, and other modules for identifying traffic. The

packet drop or forwarding decisions depend on the modules that use ACLs.

ACL types

Type

ACL number

IP version

Match criteria

WLAN client ACL 100 to 199 IPv4 and IPv6 SSID.

WLAN AP ACL 200 to 299 IPv4 and IPv6 AP MAC address and AP serial ID.

Basic ACLs 2000 to 2999

IPv4 Source IPv4 address.

IPv6 Source IPv6 address.

Advanced ACLs 3000 to 3999

IPv4

Source IPv4 address, destination IPv4

address, packet priority, protocol number, and

other Layer 3 and Layer 4 header fields.

IPv6

Source IPv6 address, destination IPv6

address, packet priority, protocol number, and

other Layer 3 and Layer 4 header fields.

Layer 2 ACLs 4000 to 4999 IPv4 and IPv6

Layer 2 header fields, such as source and

destination MAC addresses, 802.1p priority,

and link layer protocol type.

Numbering and naming ACLs

When creating an ACL, you must assign it a number or name for identification. You can specify an

existing ACL by its number or name. Each ACL type has a unique range of ACL numbers.

For an IPv4 basic or advanced ACL, its ACL number or name must be unique in IPv4. For an IPv6

basic or advanced ACL, its ACL number and name must be unique in IPv6. For a Layer 2, WLAN

client, or WLAN AP ACL, its number or name must be globally unique.

Match order

The rules in an ACL are sorted in a specific order. When a packet matches a rule, the device stops

the match process and performs the action defined in the rule. If an ACL contains overlapping or

conflicting rules, the matching result and action to take depend on the rule order.

The following ACL match orders are available:

• config—Sorts ACL rules in ascending order of rule ID. A rule with a lower ID is matched before

a rule with a higher ID. If you use this method, check the rules and their order carefully.

2

NOTE:

The match order of WLAN client ACLs and WLAN AP ACLs can only be config.

• auto—Sorts ACL rules in depth-first order. Depth-first ordering makes sure any subset of a rule

is always matched before the rule. Table 1 lists the sequence of tie breakers that depth-first

ordering uses to sort rules for each type of ACL.

Table 1 Sort ACL rules in depth-first order

ACL type

Sequence of tie breakers

IPv4 basic ACL

1. VPN instance.

2. More 0s in the source IPv4 address wildcard (more 0s means a

narrower IPv4 address range).

3. Rule configured earlier.

IPv4 advanced ACL

1. VPN instance.

2. Specific protocol number.

3. More 0s in the source IPv4 address wildcard mask.

4. More 0s in the destination IPv4 address wildcard.

5. Narrower TCP/UDP service port number range.

6. Rule configured earlier.

IPv6 basic ACL

1. VPN instance.

2. Longer prefix for the source IPv6 address (a longer prefix means a

narrower IPv6 address range).

3. Rule configured earlier.

IPv6 advanced ACL

1. VPN instance.

2. Specific protocol number.

3. Longer prefix for the source IPv6 address.

4. Longer prefix for the destination IPv6 address.

5. Narrower TCP/UDP service port number range.

6. Rule configured earlier.

Layer 2 ACL

1. More 1s in the source MAC address mask (more 1s means a smaller

MAC address).

2. More 1s in the destination MAC address mask.

3. Rule configured earlier.

A wildcard mask, also called an i nverse mask, is a 32 -bit binary number represented in dotted

decimal notation. In contrast to a network mask, the 0 bits in a wildcard mask represent "do care"

bits, and the 1 bits represent "don't care" bits. If the "do care" bits in an IP address are identical to the

"do care" bits in an IP address criterion, the IP address matches the criterion. All "don't care" bits are

ignored. The 0s and 1s in a wildcard mask can be noncontiguous. For example, 0.255.0.255 is a

valid wildcard mask.

Rule numbering

ACL rules can be m anually numbered or automatically numbered. This section describes how

automatic ACL rule numbering works.

Rule numbering step

If you do not assign an ID to the rule you are creating, the system automatically assigns it a rule ID.

The rule numbering step sets the increment by which the system automatically numbers rules. For

example, the default ACL rule numbering step is 5. If you do not assign IDs to rules you are creating,

they are automatically numbered 0, 5, 10, 15, and so on. The wider the numbering step, the more

rules you can insert between two rules.

3

By introducing a gap between rules rather than contiguously numbering rules, you have the flexibility

of inserting rules in an ACL. This feature is important for a config-order ACL, where ACL rules are

matched in ascending order of rule ID.

Automatic rule numbering and renumbering

The ID automatically assigned to an ACL rule takes the nearest higher multiple of the numbering step

to the current highest rule ID, starting with 0.

For example, if the step is 5, and there are five rules numbered 0, 5, 9, 10, and 12, the newly defined

rule is numbered 15. If the ACL does not contain a rule, the first rule is numbered 0.

Whenever the step changes, the rules are renumbered, starting from 0. For example, changing the

step from 5 to 2 renumbers rules 5, 10, 13, and 15 as rules 0, 2, 4, and 6.

Fragments filtering with ACLs

Traditional packet filtering matches only first fragments of packets, and al lows all subsequent

non-first fragments to pass through. Attackers can fabricate non-first fragments to attack networks.

To avoid the risks, the ACL feature is designed as follows:

• Filters all fragments by default, including non-first fragments.

• Allows for matching criteria modification for efficiency. For example, you can configure the ACL

to filter only non-first fragments.

Configuration restrictions and guidelines

Matching packets are forwarded through slow forwarding if an ACL rule contains match criteria or

has functions enabled in addition to the following match criteria and functions:

• Source and destination IP addresses.

• Source and destination ports.

• Transport layer protocol.

• ICMP or ICMPv6 message type, message code, and message name.

• VPN instance.

• Logging.

• Time range.

Slow forwarding requires packets to be sent to the control plane for forwarding entry calculation,

which affects the device forwarding performance.

Configuring an advanced ACL

This section describes procedures for configuring IPv4 and IPv6 advanced ACLs.

Configuring an IPv4 advanced ACL

IPv4 advanced ACLs match packets based on the following criteria:

• Source IP addresses.

• Destination IP addresses.

• Packet priorities.

• Protocol numbers.

• Other protocol header information, such as TCP/UDP source and destination port numbers,

TCP flags, ICMP message types, and ICMP message codes.

Compared to IPv4 basic ACLs, IPv4 advanced ACLs allow more flexible and accurate filtering.

Copying an ACL

You can create an ACL by copying an existing ACL (source ACL). The new ACL (destination ACL)

has the same properties and content as the source ACL, but uses a different number or name than

the source ACL.

To successfully copy an ACL, make sure:

• The destination ACL number is from the same type as the source ACL number.

• The source ACL already exists, but the destination ACL does not.

To copy an ACL:

Step

Command

1. Enter system view.

2. Copy an existing ACL to create a new ACL.

Configuring packet filtering with ACLs

This section describes procedures for applying an ACL to filter incoming or outgoing IPv4 or IPv6

packets on the specified interface.

This feature does not take effect on an interface that is an aggregation member port.

By default, an interface does not

filter packets.

You can apply up to 32 ACLs to

the same direction of an interface.

Configuring SNMP notifications for packet filtering

You can configure the ACL module to generate SNMP notifications for packet filtering and output

them to the information center or SNMP module at the output interval. If an ACL is matched for the

first time, the device immediately outputs a notification instead of waiting for the next output. The

notification records the number of matching packets and the matched ACL rules.

For more information about the information center and SNMP, see Network Management and

Monitoring Configuration Guide.

To configure SNMP notifications for packet filtering:

1. Enter system view.

packet filtering notifications.
